Leiden, Netherlands and Milpitas, CA. March 28, 2017 – IXYS
Corporation (NASDAQ: IXYS), a global manufacturer of power semiconductors and
ICs for energy efficiency, power management, transportation, medical, and motor
control applications, today announced a digital power design that demonstrates
surge voltage protection as well as inrush current and short-circuit protection
for battery powered devices based on the Zilog MCU.

This reference
design demonstrates the cost effective use of proven
Zilog MCU for digital power control, integrating IXYS power and digital control
software in one ready to use design.

Compared to hardware only solutions, digital control ones help
simplify the system and provide power designers with a greater flexibility at
the same time. This design makes use of the Z8F3281 microcontroller (MCU) from
Zilog, Inc. for digital control. It protects the load from transient voltage
spikes emanating from the battery and also safeguards the battery from inrush
current and short-circuit conditions at the load.

The load current can range from 0 to 20A, and the output voltage is
programmable from 12V to 48V, using the MCU or an external resistor divider.
The inrush current limit is set at 30A, and the surge voltage protection is up
to 150V. At a load current of 20A, the efficiency is at 99 percent in the idle
state. When the output voltage is at 24V, it becomes 99.5 and 98 percent at 48V
and 12V, respectively.

The design
consists of a power component board (3.6 x 2.6 x 1.6 inches) and
microcontroller module (1.3 x 1 x 0.5 inches). The schematics and bills of
material are also available.
